Dataset description

 PI:              James Ledwell
 of:              Woods Hole Oceanographic Institution
 dataset:         Nutrient measurements from Niskin bottle samples
 platform:        R/V Oceanus
 
 Methodology: none provided with data.  Analyses performed by Paul Henderson
              (phenderson@whoi.edu) at WHOI Nutrients Facility.

 DMO note: 
    The SiO4 silicate data were originally called SiO2; Paul Henderson 
    in the nutrients facility confirmed the data are SiO4. Cast number was 
    matched in the Niskin bottle data to retrieve event, date, time, lon and
    lat, as well as depth_n, press and depth.
